To a/ZZ whom it may concern:

Beit known that I, NORMAN R. SMITH, a

y citizen of the UnitedStates ofAmerica, and

a resident of the city of Seattle, in the county l of'King and State of Washington, have in'- vented certain new and-useful Improvements Engines, `of which vthe following Af further obj ect is tol provide improved means whereby the direction of rotation of the .y iston orY carrier can be readily changed;' ther,novel means whereby one, pressureV part during. its inward. movement movesY an-l other outward or into action.

` With these and other .obj ects in view, mad-e apparent in the following description, theinvention consists of the:novelsconstruction,.

arrangement, and combination ofparts hereinafter described and those features. of 'con` struction particularly" set forth inthe appended cl-aims.

carrier is formed with suitable cut-out portionsextending inward 'from one side face in It will be understood that the Y which the swing-frames 4 are mounted, and`I f curvedways 10 extend from these cut-out portions.- These curved Ways 10 are designed to receive the pressure parts or Wings 9, and removable plate 3 of the-carrier is formed with curved'ways 10 adapted-toregister with Ways 10`and receive the adjacent side; portions of 'said pressureparts. (See Fig. 2.,) The pressurelates carry in their outer ends rollers 11,v wffich are in continual engagementwiththe inner face of the casing 1,-

which islso shaped as to cause alternate inward andoutward movement of the pressure` plates duringv rotation of the carrier.4 TheV Ybore of the oasinghas opposite-.curved 'po"r-.V

tions a .arranged eccentrically to the center of rotation of the carrier, and the inner end'off theseportions a' curve inwardlytoward the ing opposite abutments 12. Thecarrier is formed on opposite` sides of Athe pressure- I plates with steam-channels 13 which vextend] inwardly from the sides of the carrier, saidY section 3' alsorhavingopenin s 13', which register with the channels l13 Orla purpose made apparent in the following, ,and from said channelsv 13 lead'4 smallv ductsll, which are-adaptedto deliver the steam from said channels 'without Vthe bounds of 'the' carrier beinV` 'rotated in'the'direction of the arrowv it 7 will e'observed .that the two projected pres# sure parts are being'acted upon by the'steain. When, however, the othertwo pressure parts or wings of the res 'ective pairsV pass 'abut-v ments'12, steam wi libe admitted in the rear thereof andwill'v act upon thesame before thev iirst-two-namedv pressurelpa'rts pass exhaust` ports17. The engine istherefore always,I

positively driven Vby 'live' steam, and conse-y quently made powerfulin its action.v

.Inorder to'iprevent the steam-channels 13 onboth sides ofthe pressure parts from tak-."1 o 5 ingV stearnfromfthe same ports of ingress 15;' 4

I arrange those channels on one side oi the pressure parts closer to the periphery of the carrier than those on the opposite, and those ingress-ports in the heads of the casing are correspondingly arranged, so that those ports designed to admit steam for driving the carrier in one direction will register only with those steam-channels of the carrier at the proper side 'of the pressure parts. In reversing the movement of the carrier steam is admitted through the ingress-ports 15 at the opposite side of the abutments 12, which ports will register with the other steam-channels 13 oit' the carrier, and consequently as the pressure parts pass the abutments steam will be admitted into the casing in the rear thereof.

For the purposes of reversing the engine I mount in pipe 18 a two-way valve 19, through the medium of which steam from steam-pipes 20 can be directed into either the upper or lower pairs of pipes 16, which lead to the ingress ports or grooves 15, arranged at opposite sides of the abutments 12. Further, other exhaust-ports, as 17', are formed in the casing, and either these or exhaust-ports 17 can be closed, this depending upon the direction in Which the carrier is rotated, and for the purposes of illustration I have shown two plugs, as 21, mounted on swing-frame 22, alternately closing the` respective exhaustports. A suitable hand-Wheel is connected to each swing-frame, which can be operated by the operator for swinging the frames, as is obvious.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is-
